CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 561 ,528, dated June 2,1896.

Application filed January 20, 1896. Serial No. 576,191- (No model.)

To (LZZ whom it may concern:

Be it known that I, CHARLES SCHLEIOHER, of Louisville, in the county ofJefferson and State of Kentucky, have invented certain new and usefulImprovements in Car-Couplin gs; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form part of this specification.

This invention is an improvement in carcouplings of the twin-jaw and Janney types and is an improved locking device for the swinging jawsthereof.

It is especially designed for use in couplings such as are shown in myapplication filed January 14:, 1896, Serial No. 575,497; and it consistsin the construction and combination of parts summarized in the claimsand lllllS-r trated in the drawings, in which- Figure 1 is a rearperspective view of part of a coupling, showing my improved lockingdevice locked. Fig. 2 is a horizontal section on line 2 2, Fig. 1. Fig.3 is a detail transverse section looking from the rear, showing thedevice in position to be locked in full lines and unlocked in dottedlines. Fig. 4 is a detail horizontal section showingthe device asapplied to ordinary Janney type of couplings.

In the drawings, A designates a draw-bar constructed with a rigid hookat and a swinging hook l3, pivoted to the side of the rigid hook. Adesignates part of a similar but opposite draw-bar having a rigid hook aand a swinging hook B, which, as shown, engages with the rigid hook atof draw-bar A. These parts may be constructed substantially like theimproved coupling shown in my application for patent above referred to,and therefore need no further description herein.

0 designates a lock-bar which lies in atransverse horizontal slot A indraw-bar A, just in rear of and opening into a jaw-recess, so that thelock-bar can be engaged by the inner end of the swinginghook B. Thislocking-bar has on its front side a beveled catch O,which is adapted toengage a recess 11 in the end. of jaw 13 when the latter is engaged withhook a, as shown in Fig. 1, and if the lock-bar be then looked so thatit cannot move longitudinally the jaw B will be locked to draw-bar A, asis evident from the drawings. The lockbar may also have anotherprojection C on its front edge, which will be struck by the entering endof the jaw B in the act of coupling, and thus the lock-bar be moved intolocking position. One end of bar 0 projects outside the draw-bar in rearof the head thereof and has a vertical slot or notch c in its frontface, into which drops a bolt D. This bolt is retained in a verticalposition above lock-bar O by suitable guides d on the sides of thedraw-bar, and the upper end of bolt D is connected bya link e to end ofa lever E, fulcrumed near its center on a stud E- 011 top of thedraw-bar, as shown.

To the bolt D, above lock-bar G, is pivoted a dog F, which lies on topof the lock-bar in a horizontal position, Fig. 1, when the lockbar islocked; but when lever E is depressed so as to lift bolt D dog F isbrought to a vertical position and its lower end rests in a shallownotch f in the upper edge of lock-bar C, as shown in full lines, Fig. 3,and in this position upholds bolt D so that it cannot e11- gage slot 0.Then when the lock-bar is moved inward by the uncoupling movement of theswinging jaw B dogF remains in Iupright position and the lock-bar slipsthereunder. The lock-bar is thus left in position to be moved back intolocking position freely. When the lock-bar is moved back, the lower endof dog F, resting on the lock-bar, is moved to one side until it ceasesto uphold bolt D, which then drops by gravity onto lock-bar (I and intoslot 0, securely locking the bar.

The drawings make further explanation of the operation of the deviceunnecessary.

If desired to reduce the friction between the dog and lock-bar, the rearend of the lock-bar may be tapered downward, as at C and the lower endof the dog rounded, as shown, so that the unlocking movement of the baris not seriously retarded by the weight of the dog, bolt, and leverthereon, and the loeking movement of the bar throws the dog out ofperpendicular with more certainty.

Fig. 4. shows the locking device adapted to an ordinary J annoy-typecoupling, in which, instead of a rigid jaw a and swinging jaw B, aswinging aw a having a locking-shank a is used.

The end of shank a strikes the locking-bar and is retained thereby insubstantially the same manner that jaw 15 would be retained.

Having thus described myinvention, What I therefore claim as new, anddesire to secure by Letters Patent thereon, is-

1. In a car-coupling the combination of a draw-bar and a swinging jaw,with a lockingbar, a bolt adapted to lock said bar, and a dog pivoted tothe bolt and adapted to hold the same out of engagement with thelockingbar when it is desired to uncouple, substantially as described.

2. In a swin ging-j aw-lockin g device for carcouplings the combinationof the draw-bar,

the transverse locking-bar having a slot in one end, a bolt adapted toengage said slot,

means for raising said bolt, and a dog pivoted to the bolt and adaptedto uphold it when once raised so as to leave the locking-bar free to bemoved, substantially as described.

3. In a swinging-jaw-locking device for carcouplings the combination ofthe draw-bar, a transverse locking-bar 0, having a slot 0, and taperedend; a vertically-movable bolt D, means for raising said bolt, and aswinging dog F pivoted to said bolt, all substantially as and for thepurpose set forth.

In testimony that I claim the foregoing as my own I aifix my signaturein presence of two witnesses.
